GMC Hummer EV coming to Extreme E with Chip Ganassi Racing

The electric off-road racing series Extreme E is getting another famous face. This time it's not a person, but rather a vehicle: the GMC Hummer EV. GMC announced that it will be the main sponsor for the Chip Ganassi Racing Extreme E team. With the sponsorship, GMC gets to tweak the Extreme E Odyssey 21 race SUV to look more like the Hummer EV pickup and SUV that starts production late this year. The changes are subtle but effective, with the nose getting a full-width light-bar motif. Of course the race SUV is vastly more rounded than the road-going truck. It also features a standardized chassis from Spark Racing and a battery pack from Williams. The team is able to provide its own electric motor, though, which the series limits to 550 horsepower. The GMC Hummer EV race SUV will make its competition debut alongside several other pedigree teams at the first Extreme E event in Saudi Arabia this April. Three teams are operated by Formula One drivers including Sir Lewis Hamilton, Nico Rosberg and Jenson Button, the latter of whom will be driving. Andretti United will also field a team, a familiar competitor to Chip Ganassi in other racing series such as IndyCar. As for drivers, two World Rally Championship champions will compete: Carlos Sainz and nine-time consecutive champion Sebastien Loeb. The series will feature five races and with the way the competition is shaping up, they should be very interesting to watch. Related video:

Hacker jury rigs Amazon Echo into voice-controlled remote start

A lot of automakers have smartphone apps to start, lock, or unlock a connected car. Some automakers will even let you do that with a smartwatch. Then, there's YouTube user Jryanishere, who decided to use Amazon's chatty Echo voice-controlled, internet-connected information thingy. Yes, we said thingy, because we aren't really sure how else to describe the Echo. While the Echo system has received a hearty ad campaign – featuring Alec Baldwin asking Amazon's virtual assistant, Alexa, questions and ordering socks – we think this might be the first really useful thing we've seen it do. Using a MacBook, a Raspberry Pi, an Echo, an OBDLink plug-in, and his 4G LTE-equipped GMC, Jryanishere has basically made a voice-controlled remote-start system. Now, like so many voice-controlled things, this strikes us more of an extravagance than something that's functionally worthwhile. After all, the remote start on the a GMC keyfob isn't exactly rocket science. You can check out the Echo in action up top. Jryanishere gives a pretty thorough breakdown of how the setup works in the video above, but if you're at all into this sort of technological mischief, you'll want to watch (and check out the hilariously detailed blog explaining the job).

2015 Chevy Silverado, GMC Sierra can tow up to 12,000 pounds

Think back to the launch of the 2014 Chevrolet Silverado. At the time, General Motors happily trumpeted that its fullsize pickup could tow up to 11,500 pounds when properly equipped - impressive stuff, no doubt. But now, revised tow rating practices have been put into place, called SAE J2807. And with these new methods of testing, GM can now officially rate both the Silverado and its GMC Sierra twin as being able to tow up to 12,000 pounds.
Of course, not all Silverado and Sierra models are capable of this feat. In fact, because of SAE J2807, most of the truck models have actually had decreases in tow ratings from the 2014 to 2015 model year. For example, a 2014 Silverado Crew Cab with the 5.3-liter V8, 5.7-foot box and 3.73 rear axle was rated at 11,200 pounds in 2014, but has since been reduced to 10,800 in 2015. Same goes for the Sierra.
But for 2015, both the Silverado and Sierra can be had with a more powerful 6.2-liter V8, as well as a Max Trailering Package that includes a 9.76-inch rear axle, heavy-duty rear springs, revised shock tuning, improved cooling and a new trailer brake controller. There are also four- and seven-pin, bumper-mounted connectors, a trailer hitch (duh), and a G80 locking rear differential. This configuration, with either model, is the only way you can actually tow 12,000 pounds.
